In an embodiment of the present invention, as shown in fig. 2 and 3, the key 2 includes a key shaft 21, a key cap 22, and a nut 23, the key shaft 21 is disposed in the through hole 1a, and the first tapered surface 211 is disposed on an outer peripheral wall of the key shaft 21; the keycap 22 is positioned outside the key hole 8a, and one side of the keycap 22, which is back to the key hole 8a, is provided with a limit groove 22a; the nut 23 is arranged in the limiting groove 22a, and the keycap 22 and the nut 23 are in threaded connection with one end of the key shaft 21 extending out of the key hole 8 a.

In this embodiment, the key cap 22 of the key 2 is used for a user to press and operate, the nut 23 is used for reliably locking the key cap 22 to the key shaft 21, the key cap 22 and the nut 23 of the key 2 are both fixed with the key shaft 21 of the key 2 in a screwing manner, the key cap 22 of the key 2 and the nut 23 of the key 2 are equivalent to two nuts 23 screwed on the key shaft 21, so that the key 2 can be effectively prevented from loosening by using a double-nut 23 anti-loosening principle, and the reliability of the key 2 in use is ensured.

The setting of spacing groove 22a on the key cap 22 provides the accommodation space for nut 23, makes nut 23 can the implicit expression set up in spacing groove 22a and do not have the part of protrusion spacing groove 22a notch, can promote the aesthetic property of button 2 outer tube on the one hand, and on the other hand can avoid nut 23 to be touched the rotation by the mistake and break away from with key shaft 21, leads to the not hard up problem of button 2.

In an embodiment of the present invention, as shown in fig. 2 and 3, the outer wall of the key shaft 21 is provided with a stopper portion 212; when the key top 22 and the nut 23 are coupled to the key shaft 21, the stopper 212 is abutted and stopped by the side of the key top 22 facing away from the nut 23.

In this embodiment, when the nut 23 is screwed, the nut 23 and the stopper 212 cooperate to clamp the bottom wall of the limit limiting groove 22a, that is, the nut 23 and the stopper 212 cooperate to clamp part of the limit key cap 22, so that the key cap 22 can be locked by cooperation of the nut 23 and the stopper 212, and the key cap 22 can be stably mounted on the key shaft 21.

Optionally, a position avoiding groove is formed in one side of the key cap 22, which is opposite to the nut 23, when the nut 23 and the stopping portion 212 are matched to lock the key cap 22, the stopping portion 212 is located in the position avoiding groove, and the position avoiding groove provides an accommodating space for the stopping portion 212, so that the nut 23 and the stopping portion 212 are respectively accommodated in the limiting groove 22a and the position avoiding groove on two sides of the key cap 22, and thus the overall thickness of the assembled nut 23, the assembled key cap 22 and the stopping portion 212 can be reduced, and the overall volume of the key 2 is reduced. In addition, when key shaft 21 axial displacement, keep away the lateral wall of groove and still can slide with the lateral wall butt of eaves 112 to guide the removal of key shaft 21 through the cooperation of eaves 112 and keeping away the groove, promote the stationarity when button 2 is pressed and remove.

The invention further provides wearable equipment which comprises but is not limited to a smart watch or a smart bracelet.

In an embodiment of the present invention, referring to fig. 6 in combination with fig. 2, the wearable device includes a housing 8 and the waterproof key structure in the foregoing embodiment, the housing 8 is provided with a cavity and a key hole 8a, and the key hole 8a is communicated with the cavity; the key 2 of the waterproof key structure partially penetrates through the key hole 8a and extends into the accommodating cavity.

In this embodiment, the key hole 8a is used for installing the installation sleeve 1, and at least part of the installation sleeve 1 is accommodated and limited in the key hole 8a, and can be fixedly connected with the housing 8 through clamping, screwing and other modes. Through-hole 1a has been seted up along its axial direction to installation cover 1, and through-hole 1a is used for installing wearable equipment's functional module's appearance chamber intercommunication in 8 shells. The key 2 penetrates through the through hole 1a of the mounting sleeve 1 and can be detected by the sensor group in the cavity when rotating or moving along the axial direction of the through hole 1a, the wearable device can respond to the operation of the key 2 through the functional module electrically connected with the sensor group, and further the corresponding execution of the image display, the sound production and other actions of the execution terminals such as a display, a loudspeaker and the like are controlled, so that the information interaction between the wearable device and a user is realized.
